Although studies have confirmed a direct link between police work stress and life satisfaction, the sequential pathways through which perceived social support and sleep impairment operate in this relationship remain significantly underexplored. This study investigates the direct relationship between police work stress and life satisfaction, and the independent and chained mediating effects of perceived social support and sleep disturbances, among Chinese active-duty police officers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Through a cross-sectional survey, we collected data from 803 frontline police in southeast China using four standardized scales: the Police Stress Scale, Satisfaction with Life Scale, Social Support Rating Scale, and Pittsburgh Sleep Quality Index. Statistical software (SPSS version 26.0 and AMOS version 26.0) was used for correlation analysis, structural equation modeling, and bootstrap mediation analysis. Demographic covariates were controlled to verify model robustness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All variables showed significant correlations (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.001).

Police work stress is correlated with lower perceived social support, poorer sleep quality, and reduced life satisfaction among officers. Police departments should use integrated interventions to strengthen multi-level social support and its utilization, and provide sleep health programs to improve officers\u2019 life satisfaction.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1938729","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T04:29:10Z","timestamp":1789619350000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Association between police work stress and life satisfaction: the chain mediating roles of perceived social support and sleep disturbances"],"prefix":"10.3389","volume":"17","author":[{"given":"Jiwen","family":"Qiu","sequence":"first","affiliation":[{"name":"Fujian Police College","place":["Fuzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianghui","family":"Lai","sequence":"additional","affiliation":[{"name":"Fujian Police College","place":["Fuzhou, China"]},{"name":"Department of Basic Courses, Fujian Police College","place":["Fuzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jue","family":"Deng","sequence":"additional","affiliation":[{"name":"Fujian Police College","place":["Fuzhou, China"]},{"name":"Cognitive Neuroscience and Abnormal Psychology Laboratory, Department of Penalty Execution, Fujian Police College","place":["Fuzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kunyan","family":"Wang","sequence":"additional","affiliation":[{"name":"Fujian Police College","place":["Fuzhou, China"]},{"name":"Cognitive Neuroscience and Abnormal Psychology Laboratory, Department of Penalty Execution, Fujian Police College","place":["Fuzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,17]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"493","DOI":"10.5271\/sjweh.1054","article-title":"Psychosocial stress and impaired sleep","volume":"32","author":"\u00c5kerstedt","year":"2006","journal-title":"Scand.
